CHIMNEY-CAP.

SPECIFICATION forming part of Letters Patent No. 231,463, dated August 24, 1880. Application filed August 30, 1879.

To all whom it muy concern:

Beit known that I, NATHAN U. WALKER, of W'ellsville, in the county of Columbiana and State of Ollio, have invented a new and useful Improvement in Chimney-Caps; and I do hereby declare the following to be a full, clear, and exact description thereof, reference being had to the accompanying drawing, forming part of this specification, which shows an elevation, partly in section, of a chimney cap or coping and crocks embodying my invention.

Brick chimneys are liable to be injured by rain and frost, which penetrate the crevices, loosen the mortar, and cause the chimney to get out of'plumb and fall to pieces. It is also impracticablc to give to chimneys constructed entirely of brick many desirable forms of ornamental finish. To overcome the first of these difficulties chinneys have, in some instances, been formed partially or entirely' of a single metal casting, or a single tube of fire-clay or artificial stone, and in other instances with separable caps or copings and crocks; but, owing to the nature of the means devised for securing the parts, the latter constructions have been of metal, the same being impracticable in making the articles of more frangible material, as the loss from breakage in transportation and handling was so great.

The object therefore of my invention is to produce a separable cap or coping' and crock of such construction that it may be readily made from clay, terra-cotta, artificial stone, and the like, will not be liable to be broken or rendered useless in transportation or handling, and to which any desired ornamental shape may be readily given.

To this end it consists in providing the cap or coping with the usual horizontal and vertical flanges to cover and inclose the chimney, and in addition thereto with cleats or equivalents, which form a dovetailed recess adapted to receive the expanded end or like projections on the base of the crock, and in employing', in conjunction with such a cap or coping, a crock -having an expanded or dovetailed base, as

will-hereinafter more fully be set forth.

l will now proceed to describe myinvention more specifically, so that others skilled in the art to which it appertains may apply the same.

In the drawing, a indicates the chimney cap or coping, which is formed with the vertical or downwardly-projecting flange c, adapted to inclose and protect the upper end of the chimney.

b indicates the horizontally-projecting flan ge, the extent of which will depend not only'on the ornamental iinish to be given to the cap or coping, but also upon the diameter of the crock and extent of flue-opening desired. In any case the flange b will be of sufficient Width to give a firm support to the crock and admit of the formation thereon of cleats for securing the crock.

d d indicate cleats formed on the upper surface of the cap or its tlange b on the two sides of the iiuebpening. These cleats are undercut or form a dovetailed recess, as shown, for the reception of the base of the crock.

e indicates a crock, to which any desired or- -namental shape may be given; but its base must be expanded, as at f, or given the form of a dovetail or its equivalent, in order to correspond to the recess formed by the cleats d.

The cap or coping a will, of course, be coextensive with the top of the chimney, and, it' there are several fines, should preferably be provided with vertical iianges i, or intermediate ribs corresponding to the division wall or Walls of the flues, in order to obtain a better support for the cap, while the crooks may correspond in number to the flues, in which case each crock will be held by its own lset of cleats d, or in the recess formed thereby.

In use, when the cap or coping a has been applied to the top of the chimney, which can readily be done by unskilled labor, the crooks c may be secured in place by sliding the expanded base or dovetails j' between the cleats d or into the corresponding recess or recesses on the top of the cap or coping; and, if desired, the crooks may be rendered additionally secure by the use of cement.

A cap or coping and crooks formed in accordance with my invention may be of terracotta, fire-brick, artificial stone, or the like, and will not possess parts liable to change shape in the manufacture or break off in the subsequent handling or transportation, so that loss thereon will be reduced to the minimum, and a cheap and ornamental iinish for chimneys can be had.

I am aware that protective caps or copings IOO for chimneys have heretofore been made with vertical and horizontal flanges, and that detachable crooks have been secured thereto by lugs and projections, and do not herein broadly claim the same; but in such cases lthc parts have necessarily been formed of metal, as the means of attaching the parts would not permit the use of more frangible material, such as fire-bricli,&c. Therefore,

Having thus described iny invention, and fully pointed out its essential and distinguishing` features, what I claim, and desire to secure by Letters Patent, is

l. A chimney cap or coping;` having` horizontal and vertical flanges, as at b c, and a dove-
